Is there a shortcut for closing a windows (a classbbrowser, test runner, workspace, etc?
by Mariano Martinez Peck 02 Mar '09

Something like Ctrl + W or similar. It think this would be a really useful shortcut (at least for me haha). Thanks in advance.

Squeak leadership team meeting notes for 2009-02-19
by Craig Latta 02 Mar '09

02 Mar '09

Hi-- Please contact me, directly or in this thread, with questions about the team or any of its meetings. - Attending on 2009-02-19 were Bert, Craig, Edgar, Giovanni, Igor, Randal, and Yoshiki (everyone). - Randal reports no change in status for the web team's captcha project (to enable contact between the community and the leadership team via the website, without spam). He'll ping them again. - Craig describes recent Spoon (Squeak 5) development. He's duplicating editions from a headful history memory in a the minimal memory, thereby turning the latter into a headless history memory (see [1] for design terms). Then he'll have the pair of artifacts that form the next Spoon system: a minimal memory and a minimal history memory that manages changes. Craig's available time is reduced due to paid work. - Randal and Craig describe a recent email conversation they had with Bradley Kuhn and Karen Sandler from the Software Freedom Conservancy (president and legal counsel, respectively). Randal asked for more detail from the Conservancy about how to handle the significant code contributions for which we weren't able to obtain a license (as compiled by Matthew Fulmer). Bradley is setting up a time for a conference call. thanks, -C

Morphic, Balloon, Scrollbar
by Bergel, Alexandre 01 Mar '09

01 Mar '09

Dear All, I know some of you are morphic expert :-) I am still on the quest to make Mondrian usuable in Squeak. The situation is the following: I have a window having scrollbar, and I am trying to render (using Balloon) on a canvas bigger than what the window can actually display. Balloon seems to not be aware of the part of the canvas being actually displayed. It simply try to render everything. Is my guess right? Can anyone confirm please? Is there a way to turn this on? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

[Election] Voting period is now started!
by Göran Krampe 01 Mar '09

01 Mar '09

Hi all! The start of the voting period got delayed 2,5 hours due to private stuff, sorry about that. 20.30 UTC today 432 ballots were sent out and the vote is open. The bounced addresses were NOT included. All (a few) corrections emailed to me were however included. As of this point the voter list is FROZEN. No more voters can be added, but I can help if listed email addresses are not working etc, email me in private and we can see what we can do. If you are on the bounced list that I posted earlier, email me with a corrected address. regards, Göran

Virtualization effects on the Squeak VM?
by Andreas Raab 01 Mar '09

01 Mar '09

Hi - In some of my recent load testing I noticed some interesting behavior when running Squeak (specifically the Unix VM) in a virtualized environment. I don't know if anyone else does that but I'd be curious in sharing information on that. First the setting: The measures I've taken so far was running RHEL 5.2 on VMware Player and Server hosted under Windows and compare this to a bare metal server (ESX[i] is on the list for next week). BTW, for those of you raising their eyebrows about running under Windows this setup is purely driven by customer demand so we're just trying to provide people with realistic numbers about what they can expect. So far the most interesting artifacts were the following: 1) Time millisecondClockValue and its use of gettimeofday. It turns out that in our settings, Time millisecondClockValue takes about 10% total execution time (we use it for measuring throughput so it does get called *a lot*). We will work around this by adding a low-res clock that gets updated without calling gettimeofday but it was interesting to notice how much time goes into that. 2) Socket write calls. My recent comments about socket write behavior turned out to be a virtualization effect. Running the benchmark both virtualized and non-virtualized shows a difference of 3-4 in how much time is spent in socket writes (30% virtualized vs. 8% bare metal). Keep in mind that this is running under load so we're making roughly 50k socket write requests per second with a total bandwidth of 10-20 Mbps. Has anyone seen similar effects and can confirm them? Are there other gotchas that people have observed when running virtualized servers? I suspect that the socket write issue is really the result of VMware interfacing with Windows. If anyone has seen similar effects and can share some insights, I'd appreciate it. Cheers, - Andreas

recategorize a bunch
by Sebastian Sastre 01 Mar '09

01 Mar '09

hi there, while loading some stuff of mine form an image to another, I was annoyed/surprised by not finding some methods. Then I've figured out that all not imported methods where missing because somehow they happen to be under a category named *-changed some others under *-compilation-issues. There is a way I can query the system (monticello?) to get the whole and set them another category (so I can save the packageproperly)? thanks, sebastian

is this a bug or just a limitation ?
by Mariano Martinez Peck 01 Mar '09

01 Mar '09

I am inside a method and I do ctrl + s where I have a undeclared variable. In that moment, a popup appears and I want to do "declare temp" for example. But, as I did ctrl + s I would like to go to "declare temp" with the beyboard, and then, press enter. But this, doesn't work and the popup is closed. To make this work, I have to click on "declare temp" with the mouse :( I think the most important thing I miss for others IDE is the mouse dependence we have in squeak. Just as an example, when I use Eclipse, I almost don't need the mouse and it is very fast this. Thanks, Mariano

[Election] Starting a few hours later, latest 23.00 UTC
by Göran Krampe 01 Mar '09

01 Mar '09

...because I am busy at 18.00 UTC. Sorry, I want to do this correctly, and I don't have the time right now to start it earlier - so a few hours later will have to do, at the latest 23.00 UTC. regards, Göran
